loadBatchMessages Fails for Invalid Signature only on Android

[nplasterer]

On a specific topic, I get Error: Call to function 'XMTP.loadBatchMessages' has been rejected. → Caused by: org.xmtp.android.library.XMTPException: Invalid signature
Checking out the Kotlin code, it fails here: https://github.com/xmtp/xmtp-android/blob/main/library/src/main/java/org/xmtp/android/library/messages/MessageV2.kt#L98
Two things
this syncs well on iOS, any idea how this would not fail on iOS but fail on Android? Equivalent Swift code: https://github.com/xmtp/xmtp-ios/blob/main/Sources/XMTP/Messages/MessageV2.swift#L47-L49
do you think the whole loadBatchMessages should fail in that case? Or should it just return the messages that work well (and notify there were some issues)
